Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, in particular to a ball valve. Background Art

[0002] As we all know, the ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels.

[0003] The application number is CN202222824355.5, which discloses a ball valve, including a mounting body with a flow channel, a valve stem mounted on the mounting body, a ball connected to the valve stem and located in the mounting body, and an actuator connected to the valve stem. The flow channel has two ends, and the two ends of the flow channel are respectively connected with a first butt joint pipe and a second butt joint pipe, and the first butt joint pipe and the second butt joint pipe are both sealed and fixed to the mounting body. The first butt joint pipe is provided with a first butt joint structure, and the second butt joint pipe is provided with a second butt joint structure. The utility model has the following advantages and effects: the utility model can achieve precise installation and can select different butt joint methods according to different working conditions, so that it has better practicality.

[0004] The above structure is found to be inconvenient to stably limit the driving rod during actual use. During actual use, if a child or an animal accidentally turns the handle to drive the driving rod to open the ball valve, it is easy to cause water to flood the house. Utility Model Content

[0021] During actual use, the valve body is assembled in the center of the body 1 and sealed by the sealing ring 4. Docking frames 5 are also provided on the left and right sides of the body 1 to facilitate docking of pipelines. The driving rod 3 is driven by the handle 6 to facilitate adjustment of the angle of the valve block 2. A support tube 9 is also provided on the body 1. The guide plate 8 of the handle 6 is provided between two groups of vertically arranged guide plates 8 of the support tube 9 to ensure stable opening and closing. In conjunction with the anti-misopening component, the handle 6 can be prevented from being accidentally touched by children or animals to open the ball valve.

[0022] In this embodiment, the anti-misopening component includes a spring 12, a slide plate 13 and a limit frame 14 adapted to the limit block 10. The handle 6 is in a wide-angle Z shape with an inclined surface at the center. A sliding hole is provided on the inclined surface of the handle 6. The slide plate 13 is slidably connected to the inclined surface of the handle 6. The spring 12 is arranged at an end away from the limit block 10.
